Guidance and manufacturers declaration—electromagnetic immunity
The Companion 1000/T is intended for use in the electromagnetic environment specified below. The customer or the user of the
Companion 1000/T should assure that it is used in such an environment.

Interference may occur in the vicinity of equipment marked
with the following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, ama-
teur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To asses the electromag-
netic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength
in the location in which the Companion 1000/T is used exceeds the applicable RF compliance level above, the Companion 1000/T
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the Companion 1000/T.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
* This table is included as a standard requirement for equipment which has been tested to specific test levels and over specific
frquency ranges and been found compliant with regulations.
